"He did nothing to you — what did you say to my son? To my 14-year-old son?" an unidentified woman asked the employee in the video. The worker didn't deny he was the source of the comment.
"I'm sure he's heard it before," the employee then told the woman, who headed to another area of the store in search of a manager.
